Patent JP-H11160259-A (JP)
Title: Apparatus for differential thermal analysis
Inventor: NAKAMURA NOBUTAKA
IPC: G01N25/48
Filed: 1997-11-27
Abstract: PROBLEM TO BE SOLVED: To measure a differential heat highly accurately with little irregularity by detecting a temperature difference of a sample and a reference (standard sample) from a difference of resistance values of metallic resistance body patterns formed symmetrically on an alumina substrate. SOLUTION: A temperature of a heating furnace 3 is controlled by a function generator 1 and a heating furnace temperature controller 2, so that heat can be uniformly transmitted to a sample container 6, a reference container 7 loaded on an alumina detection substrate 5 set in the heating furnace 3. However, a difference of thermal characteristics of a sample and a reference generally brings about a temperature difference between the sample and reference. The temperature difference causes a temperature difference to the containers, whereby patterns 5a, 5b of metallic resistance bodies formed symmetrically on the detection substrate 5 at the side of the sample and at the side of the reference show different resistance values.  A difference of the resistance values is impressed by a constant voltage generator 10 connected to the primary side of a bridge circuit having two sides constituted of the resistance bodies, and detected as a d.c. or an a.c. by a voltmeter 11 connected to the secondary side. The detected voltage is converted with a temperature coefficient of a resistance value of a metal forming the resistance bodies, whereby a differential heat can be measured highly accurately.

Inventor: MORINARI YOSHINARI
IPC: H01M4/84
Filed: 1990-11-28
Abstract: PURPOSE:To secure strength of a base substance for a electrode plate by adding fine powder of oxide or sulfide to molten metal in the case of pouring the molten metal of Pb or Pb alloy into a casting mold. CONSTITUTION:A drum 2 and a belt 3 having a grid 1 corresponding to configuration of a base substance on the surface are brought into contact with each other so as to rotate together. Molten metal 5 consisting of lead alloy is supplied to a molten metal injecting port 4 as base metal. The molten metal filled in the grid 1 is solidified while being sandwiched between the drum 2 and the belt 3, and is taken out as a continuous base substance 6. At this time, powder 7 of oxide or sulfide having sufficiently higher melting point and larger compressibility than Pb is injected into the molten metal 5 by using a powder feeder 9. Thereby, the powder 7 can be dispersed uniformly, and the lowering of strength of the base substance can be restricted in the case a battery is used under a high temperature, and reliability of the battery can be improved.

Title: Driving electrolytic solution for electrolytic capacitor
Inventor: MINAMI SHINICHIRO
IPC: H01G9/035
Filed: 1991-11-14
Abstract: PURPOSE:To reduce the evaporation of an electrolytic solution in a high temperature atmosphere and to prolong the life by melting SiO2 in a solution wherein tetraalkylammonium salt or tetraalkylphosphonium salt of organic acid are dissolved in gamma-butyrolactone used as a main solvent. CONSTITUTION:SiO2 is melted in a solution wherein tetraalkylammonium salt and tetraalkylphosphonium salt of organic acid are dissolved in gamma-butyrolactone used as a main solvent. Usually SiO2 in an electrolytic solution is in the form of particles of about 10mum, and the particle surfaces are charged negative. The charges form electric double layers with positive ions in their peripheries, and their mutual repulsion has made them stable. But these electric double layers are destroyed by being left alone in a high temperature atmosphere, and the SiO2 particles bond with one another reticulately, leading to the viscosity increase and gelling of the electrolytic solution. Accordingly, an electrolytic capacitor using this electrolytic solution lowers the evaporation of the electrolytic solution in a high temperature atmosphere compared with a conventional electrolytic solution, and the life characteristic of the electrolytic capacitor is largely improved.

Title: Gear pump motor
Inventor: KOMATSU KOJI
IPC: F16H57/12
Filed: 1998-11-17
Abstract: PROBLEM TO BE SOLVED: To reduce discharge pulsation by setting an inside diameter of a bearing supporting a rotary shaft of a driven gear to be larger than a shaft diameter of the rotary shaft of the driven gear and constituting the driven gear so as to be approachable to a driving gear up to a degree that a backlash formed between the driving gear and the driven gear becomes substantial zero. SOLUTION: A shaft diameter of a rotary shaft 8 extended from a driven gear 6 is set to be smaller than an inside diameter of a bush 4b. Because a gap to generate backlash between the rotary shaft 8 and the bush 4b exists, a running-in is performed. When a pressure difference is generated between suction and discharge ports by performing a pump action by a shipped gear pump motor after the running-in is terminated, force is applied to the driven gear 6 in the direction of an arrow by the pressure difference generated between suction and discharge ports and the driven gear 6 approaches the driving gear 5 till the rotary shaft 8 is abutted on the bush 4b. Therefore, backlash BR formed between the driving and driven gears 5, 6 becomes zero or substantial zero in a state that the rotary shaft 8 is abutted on the bush 4b.

Title: Permeable wall material and building structure using this wall material
Inventor: KIMURA KOZO
IPC: E04B2/90
Filed: 1995-12-15
Abstract: PROBLEM TO BE SOLVED: To take in natural wind and rain so as to obtain the same amenity as the ground even in a multistoried building. SOLUTION: Permeable wall material 10 is manufactured into a sheet state by weaving glass fiber, coated with a fluororesin layer, alternately crossing in longitudinal and lateral directions. This permeable material 10 is held from both sides by an inner frame 22 and an outer frame 24 to constitute a curtain wall W. When this curtain wall W is used as the external facing material of a multistoried building, natural wind, rain and light enter the inside through the stitches of the permeable wall material 10 so as to create environment close to nature inside. Since wind pressure acting upon the permeable wall material 10 is lowered by the permeability of the permeable wall material 10, the wind resistance design load of the curtain wall W can be set low.

Title: Electrophotographic device
Inventor: UNO MUGIJIROU
IPC: G03G15/06
Filed: 1993-12-24
Abstract: PURPOSE:To obtain an electrophotographic device capable of stably obtaining excellent image quality by arranging a preelectrifier on the upstream side in the rotational direction of a photoreceptor with respect to a static eliminator for removing a charge remaining on the photoreceptor, in an electrophotographic device using a contact electrifier controlled by a constant current. CONSTITUTION:The preelectrifier 16 brought into contact with the photoreceptor 1 through an electric conductive cloth for instance is provided on the downstream side from a transfer part 5 and the upstream side from a discharge part 7 in the rotational direction of the photoreceptor 1. The preelectrifier 16 uses developing bias supply 14 as a power source. A developing bias has the same polarity as that of a normal potential by the electrification of the photoreceptor 1. It is electrified positively in a transfer process and then, negatively by the preelectrifer 16. It is enough that the potential by the electrification at this time is negative because the photoreceptor 1 is before a discharge process. Since the photoreceptor 1 negatively electrified by preelectrification is discharged to be about 0V in the next discharge process, the potential by electrification on the photoreceptor 1 is always kept constant.

Filed: 1990-11-28
Abstract: PURPOSE: To provide a compact integrated circuit having small-sized output transistors TRs by providing an output stage which is connected to an input stage for the purpose of receiving a differential output/input signal. CONSTITUTION: The output stage consists of a P-channel TR M and an N- channel TR M2 connected between a drain voltage rail and a source voltage rail. A positive amplified and inverted differential signal VO2 which is applied to the gate electrode of a TR M4 and a negative inverted differential signal VO1 which is applied to the gate of the output TR M2 are outputted from a differential amplifier 10 which receives differential voltage signals Vin<-> and Vin<+> . Since differential outputs of the input stage are complementary, one output voltage approaches VSS when the other approaches VDD. Therefore, one of output TRs M1 and M2 is turned off while the other is made conductive. Thus, a satisfactory current driving capability is obtained with small-sized TRs.
